To integrate CBT ( Cross Browser Testing)with with Test complete and test execute.

Hi,

Please read this help section: https://support.smartbear.com/testcomplete/docs/app-testing/web/cross-platform/index.html

In a nutshell:

-- Cloud environment is configured and accessed from within TestComplete test itself;

-- Tests must be started on some local or cloud machine with TestComplete installed. TestComplete from this machine must be able to access cloud provider (CBT in your case).
